WINDOW CONSTRUCTION.

SPECIFICATION forming part of Letters Patent N0. 779,227, dated January 3, 1905.

Application filed March 29, 1904. Serial No. 200,618.

T0 all whom, it may con/067%.'

Be it known that I, EDMUND H. LUNKEN, a citizen of the United States, residing at Cincinnati, Ohio, have invented certain new and useful Improvements in I/Vindow Constructions, of which the following is a specification.

My invention relates to window constructions of the general form disclosed in an application for Letters Patent of the United States, Serial No. 173,118, filed by myself and Bernard J. Hausfeld as joint inventors September 14, 1903. In said application a main frame is adapted to be secured to the building and carries a secondary frame pivoted therein. I do not wish to be understood, however, as limiting myself to the form of window construction disclosed, as the invention may be employed in connection with other forms of window constructions than that shown in said application.

The invention consists in the features and combination and arrangement of parts hereinafter disclosed, and particulary pointed out in the claims.

In the accompanying drawings, Figure I is a perspective view of a window-opening with my invention applied. Fig. 2 is a sectional plan view taken through one side of the frame. Fig. 3 is a View similar to Fig. 2 of a modified form.

My invention concerns a main frame having one member supported by the wall of the building and supporting adjustably another member, which in turn is. adapted to carry a window part or parts-such, for instance, as a swinging frame with sliding sashes-the adjustment mentioned being intended to compensate for any settling of the building, so that in case the frame gets out of true relation to the window-opening it may be correctly set.

The main frame consists of a piece 1, preferably of metal, walled in the building and projecting into the window-opening. On this member l is supported a second member 2, adapted to carry or support a part or parts of the window. This second member of the main frame is preferably of metal, angular in cross-section, havlng one of its flanges 3 fitting against the side of the member l, where it is secured by bolts t, passing through said fiange and through enlarged openings 5 in the member l. Packing may be interposed at 6 to make a tight joint, and a washer '7 extends across the opening on the inner side of the member l, upon which washer the nut 8 rests. The bolt has a square portion at 9 fitting in a square opening in the flange of the adjustable angle-iron member. It will be clear that the said member may be set in different positions in relation to the fixed member l, the enlarged openings permitting' this adjustment, after which by tightening the bolts the angle-iron member will be set in position. Said member may also be readily removed. This angleiron member is adapted to support or carry the window parts, and as an instance of means for this end I show sockets 9 on the iiange of the angle-iron member adapted to receive the pivots on the swinging frame above mentioned.

In the above-mentioned application stopstrips are described located between the swinging frame and the main frame, and in the present case I show how these stop-strips may be supported on the angle-iron member, as at 10.

A inishing-striplQ is sprung into place between the opposing faces of the flange 13 of the angle-iron member and the wall, being retained in place by the spring tendency of the flanges 14, and a small bead 15 is arranged in the corner between the wall and the member 1 and acts as a guide for the bricklayers. The flange 13 may be directed inwardly or outwardly, Fig. 2 showing the former arrangement, while Fig. 3 shows the latter arrangement.

I claiml. In a window construction, a main frame composed of a metal frame member walled in and projectinginto the window-opening, a sec ond frame member, right angular in cross-secv tion, adjustably secured by one of its flanges and a socket and stop-strip secured to the remaining fiange of the said second member for the reception of a swinging frame, substantially as described.

2. In combination in a window construction, a main frame comprising a member to IOO be secured in the Wall ot' the building. a seci ond member, angular in cross-section, secured thereto by one of its flanges and a finishingstrip between the other flange and the wall of the building, substantially as described.

3. In combination in a window construction, a main frame comprising a member to be secured in the Wall of the building, a second member, angular in cross-section, secured thereto by one of its flanges and an elastic linishing-strip sprung into place, substantially as described.

4. In combination in a window construction, a main frame comprising a member to be secured in the Wall of the building, a second member, angularin cross-section, secured adjustably thereto by one of its langes and having its other flange extending across the edge of the lirst member, and adapted to support the remaining part of the window, and a iinishing -strip extending from said 'other flange, substantially as described.

5. In combination, the member to be secured in the Window-opening, an angular member secured by one liange to one side or' said lirst member and having its other ange cross the edge of the lirst member, and a finishingstrip extending from the latter flange to the wall of the Window-opening.

6. In a window construction, the combination of a main frame composed of a llat piece of material embedded in the Wall of the building and projecting into the Window-opening, and a frame member or' angular cross-section. litting with one of its flanges against the side ot' the flat piece composing the main frame, one of said parts having' enlarged openings therein and bolts securing the angular member to the 'flat piece and passing through the said enlarged openings, the said angular member being wholly supported by the flat piece and adjustable thereon both vertically laterally and at an inclination, substantially as described.

In testimony whereof I afiX my signature in presence of two witnesses.

EDMUND H. LUNKEN.
